A scaled and chopped version to fit two Adafruit 64x32 LED display panels and a hidden Raspberry Pi 3B+. This Github project (https://github.com/MLB-LED-Scoreboard/mlb-led-scoreboard/wiki) is at the core of it all. I also tweaked the proportions where the letters live to be a bit more representative of the actual sign's proportions.
There are a ton of OBJ files here as I had to chop the project up into multiple pieces in order to fit my printer. I took the original OBJ and went at it with a buzzsaw using Fusion 360. If you're interested in replicating this project please VERIFY THE MEASUREMENTS of you display(s). Mine were a very tight fit and if I were to do it over I'd add a couple of millimeters on the horizontal to give them a bit more space.
